WINDOW SASH AND FRME.

SPECIFICATION forming part of Letters Patent No. 333,654, dated January5, 1886.

Application filed November 12, 1885. Serial No. 182,528. (No model.)

To @ZZ whom it may concer-71.:

Be it known that I, WILLIAM E. MICHAEL, a citizen of the Unit-ed States,residing at the city of Reading, county of Berks, State of Pennsylvania,have invented a new and useful Improvement in Window Sashes and Frames,of which the following is a specification.

This invention relates more particularly to sash secured in framesunprovided with weightboxes, any of the ordinary sash-stops beingapplied to the same to lock them in positive closure or as opened tovarious heights. To this portion of the improvement I make no claim. y

The object of the improvement is to so construct and arrange a sash incombination with its frame that it may be readily removed for thepurpose of repair, painting, and cleaning without the preliminaryremoval of retaining or parting strips, the simple unscrewing of one ortwo ordinary wood-screws (according to the height of the sash)permitting the instantaneous removal of the same.

The accompanying drawings, formingapart of this specification, and inwhich like letters of reference indicate like parts, very clearly setforth the nature of my improvement, in which- Figure l representsinfront elevation awindow-frame and set of sash provided with myimprovement. Fig. 2 is a Vertical section on the line a b of Fig. l.Fig. 3 is a plan on the line of the top of the lower sash with the topsash drawn down to the same level, showing the frame in section with thesash in place; Fig. 4, the same plan with the lower sash in the act ofremoval from the frame, the latter in accordance with my improvement ofdouble parallel sash-grooves. Fig. 5 shows the application of myimprovement to the ordinary sash and frame, with the lower sash in theact of removal from or introduction Within the frame; Fig. 6, a detachedplan and side elevation,upon an enlarged scale, of the stile-hinge andits arm for securing the divided stile in swinging contact with thesash; Fig. 7, a detached plan and side elevation of the rail,hinge-seat, and stop; Fig. 8, a cross-section of the divided stile,showing the screw for retention and release of the sash from the frame;Fig. 9, a front elevation of the divided stilestrip with its hingesattached.

A represents the window frame, which, when it is constructed inaccordance with my invention, has two semicircular parallel grooves orrabbets, A', formed in the sides of the same, as shown in section inFigs. 3 and 4, for the reception of the sash. A parting strip is notused. A stop-bead, A2, is secured to the frame in front of the uppersash and extends the whole height of the frame. The usual re-enforce,A3, is made part of the sill upon the inside of the frame.

B represents both the upper and lower sash, the stiles B of which aredivided vertically at an angle of about thirty degrees, forming swingingstrips B2, which are secured at both ends, in contact with B by arms Cof hinges C, having fulcrum-points C2 upon the rails B3, said hingesresting upon hinge-plates D, provided with a correspondingfulcrum-point, D', and a stop iiange or ledge, D2, with asecuring-screw, D3. The plates D are sunk within the face of the railsB3, of such depth that when the hinge C is in contact therewith the faceof G and the rail B3 shall be level with each other. The arm C is letinto the divided sti1e-strip B2 until its face is even with the face ofthe strip, and is secured to the same by screws G3. Both stiles of thesash are made conveX,to fit the grooves A' in the frame. The hinge andits seat are set with their outer edges fiush with the outer faces ofthe sash rail. The iiange D2 permit-s an inward, but prevents anoutward, movement of the sash, and the releasably locking screw E whenin place prevents any displacement of the sash from the outside of thebuilding.

lThe hinge and seat may be made of any suitable metal. I prefer to stampthem out of sheet-brass, and subsequently drill and bend them to form.

This improvement is applicable to the ordinary sash and frame, as shownin Fig. 5. It is only necessary to round off the outer corners of thestiles and increase the depth of the beadstop and parting-strip,dividing the stile at an angle, as before, so that the division ICO theknot in the inner face, and a sub-groove would be sunk in the face ofthe frame for the cord to lie in, so as not to interfere with themovement of the sash. I prefer, however, to apply the improvement to theordinary frame without sash-weights to balance the sash, depending uponstops F, placed conveniently upon or Within the same,to hold the sash ina raised position and to retain it in a closed position.

This improvement will be of value to both builders and housekeepers, asit does away with all risk of life in cleaning the glass, and willcheapen the cost ofhouse-cleaning bythe saving in time to do the work,while the rst cost of construction will be less than with the presentframe and sash. The grooves in the frame will be run in under theplaner, and the outer edges of the stiles will be done in theplaningmill under suitable machinery.

To use the device, after the sash has been provided with thestile-strip, and the same has heen hinged thereto, as described, thesash is taken in hand and the stile Binserted in the groove A, orbetween the parting-strip and .inside stop bead of the old-style frame,as

shown in Figs. Ltand 5. The stile-strip B2 is then swung inward, and asthe stile B is pressed into place the stile-strip B2 is guided into itsgroove or recess, and the hinge contacts with the ledge or flange D2,and the sash is in place. The retaining-screw E is then screwed honie,and the sash may then be used as any ordinary sash. To remove thesash,the screwE is released from the piece B2, and the sash pulled toward theoperator, when it immediately assumes the position shown in Figs. et and5. and is lifted to one side.

Having shown the construction, use, and advantages of my improved sashand frame, I desire to claim as follows:

bottom rails of said sash, the stile-strip in its L normal state incontact upon the line of division and removably secured in such positionby a screw, E, in combination with a suitable frame, as described;whereby said sash is readily removed and replaced, as and for thepurpose specified.

3. As a new article of manufacture, hingeplates C, provided with armsC', pivoted aperture C2, and securing-holes G3, combined with hinge-seatD, its ledge D2, pivotal hole D, and securing-hole D3, substantially asshown, described, and for the purpose set forth.

4. As an improvement in window sash and frames, the combination,essentially, of the following elements: a frame, A, with parallelvertical grooves A', bead stop A2, sash B, with divided stile B2, hingesC C', and plates D D2, fulcrumed at G2, and securing-screw E, allarranged and combined to make a readily removable and replaced sash, asshown, specitied, and for the purpose set forth.
